Unable to route from North Carolina to Massachusetts

Postby Riamus » Wed May 15, 2013 1:05 pm

Whenever I try to route from North Carolina to Massachusetts using either the Android app or the Live Map, it is unable to find a route from North Carolina to Massachusetts. I saw a post at one point here saying there was a 1000 mile limit (not sure if that's still the case), but this is only about 700 miles. I'm guessing some road somewhere is messed up. Is there any way to easily find where it is failing without checking a bunch of different locations to find where routing stops? If you check on Google's maps, it provides 3 routes and the one I am really interested is goes up I-81 to avoid going through or right around DC as that's often a hassle. It's a longer route, but worth not having to sit in traffic.

If checking routing to a lot of locations along the way until you find where routing stops is the only option, I'll do that. But if there's some faster method, I'd appreciate any help. For now, just a route between the states without worrying about address should be enough as the result is the same no matter what address I enter. Note that I also tried NC to NY and NC to NJ and those failed as well. Thanks.

Could you provide some further details? Is the origin "East Norriston" or "East Norriton"? Can you provide the general destination? Waze can find a route for me from East Norriton to Winsted, CT.

Did this issue ever get resolved? Yesterday I tried to route from my current location in East Norriston, PA to my home in NW CT. Waze could not find a route. To resolve it I chose to route to Waterbury, CT then after about 45 minutes of travel I was able to reroute to my home.

That was it! I had avoid toll roads marked. Unfortunately, it doesn't appear to want to give me any alternate routes... routing server timeout error. So it wants to take me the route I really don't want to go. And it's strange that if I put in a stop in somewhere like Hagerstown, MD (it would keep me from going through DC), it shows the stop as a flag, but the route never changes. Am I doing something wrong, or will I just have to ignore the directions as I drive until it finally changes to the route I want?

I'd like to confirm exactly what's different between the circumstance where a route is returned and where it isn't. Could you confirm that under your navigation settings that "Avoid toll roads" and "Avoid major highways" are not checked and that "Type" is set to fastest (I also have "Dirt roads" set to don't allow, but don't think that should make a difference here)?

Thanks. Yeah, I'll probably send it once I get past the problem in CT. But by that time, I am most of the way there. Oh well. It won't be the only time I drive up there. Maybe when I go next year, Waze will find the route. :)

True. Usually the problem isn't that waze won't return a route at all, but rather that waze routes well out the way to stay on the interstate. I'm not sure why waze can't route to Boston, there has to be interstates from DC to Boston.

Note that you can use the send option to share your drive if you don't need to get the destination location from the person that you are providing the ETA.

My understanding is that it would overtax the processing resources to consider every possible route between the start point and the destination. Thus, waze only considers primary roads in the middle of long routes to make the processing time reasonable. What makes a road non-primary resulting in it being culled from consideration in the middle of a long route at this time seems to be the road type designation. At one time waze posted the following regarding routing penalties:
Long Distances:

0-15 km - All road types are allows for routing.
15-20 km - All road types except Streets.
20-30 km - All road types except Streets and Primary streets.
30-200 km - Only Minor, Major, and Freeways.
more than 200 km - only Freeways.

This was never crystal clear and I think there have been changes, but there are certainly issues with waze not being able to route directly from point A to point B, when point A and point B are far apart and not directly connected by roads designated as a freeway on the waze map. A need to traverse primary streets or regular streets in the middle of long routes can cause problems. I agree that the routes you are looking for should be interstate/freeway almost the entire way, but sometimes its only a few non freeway segments that cause the problems. The symptoms of this problem are exactly what you are experiencing, you can route each leg of the trip with waze just fine, but waze won't route the entire trip. In an effort to solve this problem, Waze is working to adjust how they identify primary roads so that the road type is not the only consideration .

Could you explain what you mean regarding road type long distance routing? What is different between that and counting the mileage from point A to point B to determine what is too long? Are there different lengths of roads you can be on based on type? If so, what might those be and why would they be different? I mean, if I have to drive 500 miles on a highway or 500 miles on a secondary road, the routing shouldn't be affected all that much. And if anything, it should be easier to route a long highway trip such as this would be than to route a long trip using secondary roads due to fewer roads involved. I'm just wondering how that works.

Also, that seems a little strange as well because routing from Allentown, PA to Bridgeport, CT also fails. If I can route 1100 miles in almost any direction, why wouldn't I be able to route a couple hundred miles? Are the road types in CT set up to be nothing but Parking Lot Roads and Ramps? I know they aren't; I'm just wondering how the route taken wouldn't work there if I can route further in other directions. It should be interstate almost the entire way, or at least US Routes with maybe a few State Routes thrown in. Almost no side streets except at the beginning and end of the route.
